Abstract (en)

[origin: WO2020041822A1] A method of validating a test for estimating the organic carbon content of soil or changes in organic carbon content of soil over time in which a first sample of soil is taken from a selected location and heated using Loss On Ignition (LOI) to remove organic carbon, the method comprising the steps of taking a further sample of soil from an adjacent location, the sample having minimal organic material content. A predetermined quantity of an organic material is added to the further sample to provide a second sample which is heated using Loss On Ignition (LOI) with the change of weight of the second sample determining whether the test of the first sample yielded a valid estimate of the organic carbon content of the first sample. Apparatus (10) for use in performing the method is also disclosed.
